1 Claim.

This invention relates to a ring and its mounting in a sheet metal wall. The preferred application of the ring consists in mounting it in a metallic wall of a container, whereby the ring serves as a support for a bung and when so mounted the ring becomes a permanent part of the container. Accordingly, while the invention, in this specific application, relates to a container, reference in the following disclosure to a container or to the ring as a bung ring is not to be understood as limiting the invention in its broader aspects.

One object of the invention is to construct an improved ring capable of being readily and economically manufactured.

Another object of the invention is to provide an improved ring and mounting therefor in a metallic wall, whereby it may be fixed against turning or looseness, to adequately provide for sealing gaskets to prevent leakage and provide for the application of different kinds of sealing devices.

A further object of the invention is to provide an improved ring capable of being rigidly mounted in a metallic wall against endwise and rotative a neck or embossment of the wall as a part of the ring mounting is entirely eliminated, thereby reducing the cost and simplifying the manufacture of containers, as well as permitting the ring to be mounted in cheap grades of sheet metal.

Other objects of the invention will be apparent to those skilled in the art to which my invention relates from the following description taken in connection with the accompanying drawings, wherein Fig. 1 is a view partly in elevation and partly in section of a ring having a cylindrical wall arranged to be shaped for mounting in the wall of the container.

Fig. 13 is a plan view of the sealing device shown in Figs. 10, 11, 12 and 12a.

Fig. 14 is a section on the line ld-M of Fig. 13.

In the drawings, 9 indicates an annular member or ring which is to be shaped by a suitable die mechanism (not shown) ready for mounting in a metal wall a of a container A (see Fig. 4a).

The ring 9- is shown in Figs. 1 and 2 and consists of a body portion 9a having atone end an axially extending cylindrical wall so and a laterally extending fiange 9c; and by preference the flange may be provided with one or more ears 9d which are curved laterally to serve as sealing elements, as later set forth. Two ears are shown arranged in diametric relation. The ring 9 is preferably a forging, and before it is subjected to the die mechanism, (a) the opposite sides of the axially extending wall 9b are machined to make the wall relatively thin and of uniform thickness throughout its length axially of the ring; (b) the exterior Wall of the body portion 9a is acted upon by a suitable tool in a well known manner to form a groove I 3 therein whereby is provided a shoulder I3 for a purpose later set forth; (0) the interior wall of the body portion 9a is threaded to receive a threaded member, such as a plug !4 (see Figs. 9, 10, 11 and 12); (d) an annular groove I5 is formed in the flange to receive a gasket I6 (see Figs. 5, 6 and 9) and (e) each ear 9d is formed with an opening ll. As shown, the wall 9b extends from the body portion 9a at a point outwardly of its inner wall, so that when the wall is polygonally shaped, as later set forth, all portions thereof lie between the inner and outer side walls of the body portion.

However, it will be obvious that one or more of may be carried out thereon after the ring has "tion of the wall 9b.

been acted upon by the die mechanism. The die mechanism is arranged to engage contiguous portions of the wall 9b and force them inwardly radially, as shown at 9?) in Figs. 3, 4 and 5, thereby imparting to the wall a polygonal shape or contour.

The metal wall, in which the ring is to be mounted, is formed with an opening 3|, such opening being similar in shape and size to the outer periphery of the shaped wall 9b" (see Fig. 4w). This wall a is here shown as a head for a container A, but the ring may be mounted in the side wall or body 32 of the container. Next, a gasket I6 is ringed on the wall 9b within the gasket groove l5 and the wall 9b inserted in the opening 3| as shown in Fig. 5. Finally, the wall a and ring 9 are positioned in a press of any desired construction carrying suitably shaped die members, which are relatively moved to efiect their engagement with the ring and wall 9b, to swage the marginal portion of the latter over into engagement with the wall a, as shown at Sbat in Figs. 6, 7, 9, 10 and 12a, thereby securely clamping the wall a around the opening 3| between the flange 9c and, marginal por- It will thus be seen that the ring issecured to the wall a against movement axially of the ring and by engagement of the flat faces or sides of the wall 91) with the correspondingly shaped walls of the opening 3|,

the ring 9 is held against 'rotative movement.

Such securing permits a plug M or other device, when screwed into thering 9, to be adequately tightened by means of the usual tool and removed from time to time without danger of affecting the fixed relation between the ring 9 and wall a. This fixed relation is such as to sealthe joint between these parts, but due to danger of rough or imperfect material and wear of the dies, the gasket I6 is used to insure a sealing under all abnormal conditions.

Where the wall a is to be used as the head of a barrel or container, its marginal portion is connected to the body thereof as by double seaming, as shown at 33 in Figs. 5, 6 and '7. In such application of the ring, that portion of the wall a surrounding the opening is preferably ofi-set outwardly, into a plane parallel to the remaining portion of the head, equal to the thickness of the swaged-over portion 9hr so that the latter will not project into the container beyond the head tothereby insure the complete drainage of the container; also, the wall a may be provided with an annular up-standing embossment a when desired.

The ears 9d permit a section of wire .34 to be threaded through them and one or more openings formed in portions of the plug l4 and their. ends secured by a lead slug 35. As illustrative of such sealing means, the plug I4 is formed with. a recess 36, preferably of polygonal shape, for

a suitable tool and two side walls of this recess are formed with inclined through-openings 3'! through which the wire 34 passes.

When desired, the sealing may be efiected by means of a cap 38 formed of thin sheet metal and capable of ready distortion or mutilation to detect tampering and to prevent its re-application to the ring. The cap 38 is substantially cup-shaped to fit over the collar or wall l3, and permit its side wall or skirt to be circumferentially crimped into the groove l3 around and below the shoulder l3. The skirt of the cap. 38 may be long enough to accommodate the flange l4 on the plug M, as shown in Figs. 10, 11 and 12. Where the plug [4 is omitted, as shown in Fig. 12a, or the flange on the plug is omitted so that when the plug is screwed into the ring its outer end is substantially flush with the upper end of the ring, the cap 38 may engage a gasket 39 positioned on the upper end of the ring to seal the opening. But if such plug is provided with a gasket then the gasket 39 may be omitted if desired.

The cap 38 is preferably embossed with two relatively shallow continuous grooves 46 extending from the lower edge of the skirt at one side upwardly along the skirt across a portion of its top wall and down the adjacent portion of the skirt to its lower edge and also with a groove 4| connected to or intersecting the grooves 40. These grooves facilitate mutilation of the cap (see dotted lines 42 in Fig. 12) when it is desired to remove it. The central portion of the top wall of the cap may be embossed, as shown at 43, to dispose it above the marginal portion of the wall, which further facilitates the mutilation of the cap.

To those skilled in the art to which my invention relates, many changes in construction and widely difiering embodiments and applications of the invention will suggest themselves without departing from the spirit and scope thereof. My disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting.

What I claim is:

Means for securing a bung ring in non-rotative engagement with a metallic wall of a container, comprising a polygonal opening formed in said wall, and a bung ring, said bung ring consisting of an internally threaded body portion having a flange overlying the wall adjacent to and surrounding said opening and provided with a relatively thin, depending polygonal skirtto permit the use of metallic material for said wall devoid of drawing characteristics, said skirt being complementary to the sides of said opening and extending therethrough and swaged over and upon the said wall in opposition to the said overlying flange,
